It should be noted that pages 18-19 are missing.
And, the front matter is out of order. The pages
are not the order shown in the Table of Contents.
There is a third edition available on the web
and the 2 pages appear to match, i.e pages
17 and 20 match exactly.
It is a good idea to check scanned material
especially, as in this case, copies proliferate.
